Abstract

The objective of this study was to evaluate the prognostic impact of genomic regions in a series of human immunodeficiency virus (HIV)-related diffuse large B-cell lymphomas (HIV-DLBCLs) and post-transplant DLBCLs (PT-DLBCLs) analyzed by genome-wide DNA profiling. Minimal common regions (MCRs) were estimated on genomic profiles obtained using Affymetrix Human Mapping 250k Nsp I arrays and tested for their impact on clinical outcome by univariate analysis on 36 PT-DLBCLs, 19 HIV-DLBCLs and, as a control group, 149 DLBCLs arising in immunocompetent individuals (IC-DLBCLs). PT-DLBCL and HIV-DLBCL presented a similar outcome. Immunodeficiency-related DLBCL (ID-DLBCL) had a worse overall survival (OS) than IC-DLBCL. Seven MCRs showed a statistical impact on OS in PT-DLBCL and four in HIV-DLBCL. Among these, the presence of gains at 1q or at 18q defined a group of patients with PT-DLBCL with a very poor outcome (p < 0.0001). The presence of del(3p14.2) or of + 2p23.1 identified a group of HIV-DLBCLs with a very poor outcome (p = 0.0072). It was concluded that genomic aberrations affecting outcome differ between ID-DLBCL and IC-DLBCL and are also dependent on the type of acquired immunodeficiency.
